Embodiment Construction
[0044] Some embodiments of the present invention relate to dynamic random access memory (DRAM for short), more specifically but not limited to, a method and system for managing DRAM.
[0045] An aspect of some embodiments of the present invention relates to a system, apparatus, and method for mapping a bank cluster of DRAMs to a common virtual machine running on a host operating system (OS) of a host computing device An application executed on a virtual machine (VM for short). Each bank cluster is used exclusively by each mapped application.
[0046] A virtual machine monitor running the common VM performs the mapping of bank clusters of the DRAM by translating the mapping of each cluster into physical addresses provided to a memory controller controlling the DRAM. The virtual machine monitor maps guest physical addresses used by the VM to physical addresses of the DRAM controlled by the storage controller.
[0047] When multiple VMs are running on the host OS of the host co...
